Description

Spring pliers

The invention relates to a device with which the ends individual strings are attached to the frame of a racket for a ball game, referred to here as spring pliers will.

Fastening devices for securing the ends of individual ones Strings on the frame of a racket for ball games are already known, as from the British description 23 260 of October 31, 1908, British description 887 526 of December 19, 1958 and from US-PS 3 994 495.

The state closest to the present invention the prior art is disclosed in U.S. Patent No. 3,994,495 referenced which has a pair of opposed tapered ones Wedges are disclosed which are received within a tapered passage or hole in the racket to tightly wedge-engage the end or tail portion of the string and the string to the frame of the racket for the ball game. The one who has tried to use such known wedges is known to be quite small and heavy handle and align with the string before inserting it into the tapered hole with the string will. To align the wedges with the string, the

130050/043 *

Fingers of both hands are used, and once aligned, the wedges need to be removed from the fingers of only one hand be taken over so that the user has the other hand free to hold the string while the wedges moved along the string and first inserted into the tapered hole. It has been shown that when handing the wedges from the fingers of both hands to the fingers of only one hand, often a wedge or wedges be dropped so that the aligning operation is inevitable The wedge and string have to be started all over again. This can be a very time consuming and tedious process which often leads to despair of the person who wants to do the covering. The difficulty that the Handling such wedges caused probably a major contribution to the use of such wedges in the covering of racket frames have not found a wide field of application.

Another difficulty with these known wedges is that the wedges to achieve an effective Wedging action axially aligned with one another and on diametrically opposite sides of the string Need to become. If the wedges are not properly aligned, there will be no effective wedging and the clamped string tends to loosen when tensioned, so that the string is pulled out of the hole. In this case, the stringing process must be repeated, which is tedious and expensive when it is in the Factory takes place in the manufacture, but is even more troublesome and harmful to the sale of clubs when it is occurs after the club is acquired and during play.

Another difficulty with the known wedges is that, like the British description already mentioned 23,260 and U.S. Patent 3,994,495 show after the initial

130050/0433

Insertion of the wedges into the tapered hole generally requires a separate wedge insertion device in order to achieve the Drive wedges all the way into the tapered hole so that they wedge the string and clamp it to the racket frame. The use of such wedge inserters adds additional manufacturing process steps necessary, which increases the cost of the covering and additional skill of the staff is required, which can lead to further fatigue and prustration of the staff.

The object of the invention is to solve the aforementioned difficulties in the prior art with wedges for clamping the Ends of individual strings on the frame of a racket for ball games by creating appropriate spring pliers to avoid.

In one embodiment, the spring pliers according to the invention has a pair of opposing, tapered ones Wedges and a pair of spring-nosed handles attached to the rear ends of the wedges and align these axially substantially diametrically to one another. When opening the spring-nosed handles a string can be accommodated within the wedges, and after closing the pliers-like straightening Handles the wedges axially on diametrically opposite sides of the string. The nipper-like Handles are easy to manipulate with the fingers of just one hand, around the aligned wedges along the string to move and insert into the tapered hole, which is formed in the racket frame, so that the Kei-Ie Wedge the string and clamp it to the racket frame. Then the spring-nosed handles can easily and easily broken off and removed from the inserted wedges by facing the inserted ones Wedges are moved back and forth to remove them from the

1 and 2 is a first embodiment a spring pliers 10 according to the invention is shown. In cross section is part of a frame F of a racket for To see ball games, through which a tapered passage or a hole T extends, in which the end portion a string S for stringing the racket is jammed under the action of a wedge.

The spring forceps 10 may have a pair of opposing, tapered wedges W1 and W2 that end with of the string S wedge-engaged to secure the end portion of the string to the frame F when the Wedges are inserted into the tapered hole T as shown in FIG. Furthermore, the spring pliers 10 include a pair of pliers Device, for example a pair of opposing handles H1 and H2, their front areas are attached to the rear areas of the wedges W1 and W2, for example by being in one piece with these are designed to align the inner surfaces of the wedges axially and at an angle in relation to one another- * and to make them flee. The rear areas of the handles are attached to one another by, for example are integrally formed with a web V / 3, which forms a pivot point that enables the pliers-like movement of the wedges and handles.

The inner surfaces of the wedges W1 and W2 and the handles H1 and H2 together form a passage or a guide P which extends through the wedges and the handles and picks up the string S when the wedges and handles are in a pincer-like motion about the pivot point or web W3 in the direction of arrows 12 and H according to FIG

130.060.

are spread out. When the wedges and handles are closed around the pivot point or web V / 3 in a pincer-like movement, the inner surfaces of the wedges W1 are aligned and W2 are axially aligned with the string and with each other and are angularly diametrically opposed to each other.

The handles H1 and H2 can easily be grasped by just one hand of the user in order to remove the wedges to move along the string in the direction of arrow 16 according to FIGS. 1 and 2 and the end portion of the string in insert the tapered hole T to clamp it to the frame P and fix it there.

When the wedges W1 and W2 are inserted into the tapered hole T, the handles H1 and H2 can be moved back and forth by the user in relation to the inserted wedges in order to separate the handles from the wedges and since with the attachment of the string to the frame P. of the racket to complete. To make it easier to break off or detach the handles H1 and H2 from the wedges V / 1 and V / 2 used, the spring pliers 10 can also have intermediate areas 11 and 12 between the rear areas of the wedges V / 1 and V / 2 and the front B -: - ^ some of the handles H1 and H2 are provided and a.i. have a weakened cross-section. Since these intermediate areas 11 and I2 have a reduced cross-section compared to the cross-section of the wedges V / 1 and V / 2 and the handles H1 and H2, they can be easily broken off and make it easier to separate the handles H1 and H2 from the inserted wedges V / 1 and V / 2.

As can be seen from FIGS. 1 and 2, the inner surfaces the parts V / 1 and V / 2 be serrated or fluted to encourage the Xuile engagement with the string, and the rear Areas of the handles H1 and H2 can be knurled to make it easier for the user to grasp the handles.

lighten.

The structure of the spring pliers 10 according to the invention can be seen in detail from FIGS. 3-5 and in particular from FIG. 6, which shows the spring pliers 10 spread in the direction of arrow 18 to the structural details and the design of the inner surfaces of the wedges W1 and W2, the Between areas 11 and 12 and the handles H1 and Make H2 clear.

In particular, it can be seen that the opposite, spaced apart, tapered wedges W1 and W2, substantially conical outer surfaces 21 and 22 (Fig. 4) and essentially cylindrical, opposing inner surfaces 23 and 24 (Fig. 6) which have a first pair of opposite one another Form grooves 26 and 27 which extend overall in the longitudinal direction of the wedges. According to Fig. 6 have the wedges also have a first and a second pair of opposing, spaced apart, overall longitudinally extending edges 30-30 and 32-32.

As can be seen most clearly in FIGS. 4 and 6, the handles H1 and H2 consist of two opposite one another Spaced, overall in the longitudinal direction extending, semi-cylindrical handles, which in the direction are tapered to each other (Fig. 4) and are linearly aligned with the wedges W1 and YJ2, as Fig. 4 shows. The handles each have essentially a cylindrical outer surface 38 and 39 (Fig. 4) and essentially cylindrical, opposing inner surfaces 41 and 42 (Fig. 6) which have a second pair of opposing Have grooves 43 and 44 which extend overall in the longitudinal direction of the handles. According to Fig. 6 are the handles H1 and H2 also have a first and

AS-

second pair of opposite, spaced apart, overall in the longitudinal direction extending edges 46-46 and 47-47.

The intermediate areas 11 and 12 (Pig. 4) are between the rear ends of the wedges W1 and W2 and the front Ends of handles H1 and H2 are provided as Pig. Figures 4 and 6 show and may be formed integrally therewith as can be seen in the drawing. The intermediate areas H and 12 are essentially cylindrical Outer surfaces 51 and 52 (Fig. 4) and substantially cylindrical, opposed inner surfaces 53 and 54 (Fig. 6) which form a third pair of opposed Grooves 56 and 57 (FIG. 6) form which extend overall in the longitudinal direction of the intermediate regions. The intermediate areas or links are further provided with a first and second pair of opposing, at a distance from one another and extending overall in the longitudinal direction edges 58-58 and 59-59 provided.

According to FIG. 5, the web W3 has a substantially semicircular shape Shape with a substantially cylindrical outer surface 61 and a substantially cylindrical inner surface i-3 62. In Fig. 6 it can be clearly seen that the web ¥ 3 with the handles H1 and H2 at their rear ends between the rear ends of the second pair of edges 47-47 provided on the handles H1 and H2 in one piece can be formed. As already mentioned, the web W3 forms a pivot point, which it the wedges W1 and W2, the Between areas H and 12 and the handles H1 and H2 makes possible in the direction of each other and each other to be swiveled away resiliently like pliers.

According to FIG. 6, the two opposing grooves 26 and 27 on the inner surface of the wedges W1 and W2,

130050/0 ^ 33

the two opposing grooves 56 and 57 on the inner surface of the intermediate areas H and 12 and the mutually opposite grooves 43 and 44 on the Inner surface of the handles H1 and H2 together form the longitudinally extending inner guide P, which is shown in FIG 1, 2, 4 and 5 can be seen and that of FIG. 4 from the rear end of the handles to the front end of the wedges is gradually tapered inwards.

According to ^ ig. 4 and 5 are the first two spaced apart, overall longitudinally extending edges 30-30, 58-58 and 46-46, which are attached to the wedges ¥ 1 and W2, the intermediate areas 11 and 12 and the handles H1 and H2 are provided, are generally linearly aligned and together form a slot 60 which extends in the longitudinal direction over the entire length of the wedges, the intermediate areas and the handles. The slot 60 is tapered inward as a whole from the rear end of the handles to the front end of the wedges, the rear region of the slot being wider than the diameter of the string S and the front region of the longitudinal slot being narrower than the diameter of the string S. Furthermore, be pointed out that, as also shown in FIG. 5, the slot 60 is open along its entire length in the entire length of the guide ρ and the ^ aite S offers access to the guide P.

\ Lenn. the string is inserted into the further section of the longitudinal slot 60, as shown in FIGS. 1 and 4, particularly FIG. 1, and the string is pressed against the opposite edges which make up the narrower front region of the slot 60 the wedges, intermediate areas and handles are pivoted away from one another in a pincer-like movement around the web W3 in order to open the narrower area of the longitudinally extending slot 60,

so that the string can be received in the guide P. When the wedges, intermediate areas and handles around the bridge have been pivoted towards each other again in a pliers-like movement, the guide P aligns the respective inner surfaces of the wedges, intermediate areas and handles with respect to the string S in the interior. When the string is received in the guide P inside, the outer surfaces of the handles H1 and H2 can be grasped with only one hand of the user, the spring pliers 10 pushed along the string and the wedges can be inserted into the tapered hole T, which extends through extends the frame F of the racket. When, as already mentioned, the wedges are inserted into the tapered hole and the handles are moved back and forth with respect to the inserted wedges, the intermediate areas with reduced cross-section break off from the rear ends of the wedges, so that the intermediate areas and handles are separated from the inserted wedges be separated.

Fig. 7 shows a further embodiment of a spring pliers according to the invention, in which the handles H1 and H2 are each provided with radially outwardly projecting projections 64 and 66 (see also FIG. 8), which are shown in FIG lie in a plane which is essentially perpendicular to the inner surfaces 23 and 24 of the wedges V / 1 and V / 2, respectively.

The projections 64 and 66 are used to determine the position of the Handles H1 and H2 opposite the hand of the user in order to move the handles in relation to the used ones Wedges V / 1 and V / 2 (Fig. 2) in an arc which is essentially in a plane parallel to the opposing ones Inner surfaces 23 and 24 of the wedges are located to facilitate. This is to reduce the risk that the inserted wedges recover due to a movement due to the breaking off of the intermediate areas from the wedges remove from the tapered hole T. It has been found that when the

• Λ *

Handles Η1 and Η2 in an arc that is essentially lies in a plane perpendicular to the opposing inner surfaces of the wedges, the wedges tend have to withdraw again from the tapered hole T. and thereby reducing the clamping or wedging effect of the wedges when securing the string in the frame P. or cancel entirely.

Like from Pig. 7 it can be seen, the opposite Inner surfaces 23 and 24 of wedges W1 and W2 inward from the rear to the front of the wedges be tapered so that the inner surfaces 23 and 24 of the wedges W1 and W2 after opening the wedges, the intermediate areas and the handles in the already described pincer-like movement essentially parallel to one another extend what the alignment of the inner surfaces of the wedges W1 and W2 with the string S after receiving the same in the guide P facilitated.

Based on Pig. 1 and 2 should also be noted that the tapered hole T either directly in the frame F of the Racket designed or designed as a tapered inner passage that extends through an eyelet or an eye extends which is disposed in a cylindrically shaped opening through the frame F of the Racket protrudes.

It is also clear that after the wedges W1 and W2 into the tapered hole T by the user's grasping of the handles H1 and H2 and after application of tension (in the direction of an arrow 68 in Fig. 2) on the string S, for example by means of a stringing machine In a typical stringing operation of a racket, the wedges W1 and W2 are further tapered into the The hole can be driven in or inserted in order to become wedged more tightly with the string and make it more firmly attached to the string

To attach frame P of the racket.

In Figs. 9-12, another embodiment is one According to the invention, spring pliers 100 are shown, which have three wedges W1, V / 2 and V / 3 and three handles H1, H2 and H3, with which the inner surfaces of the wedges are axially and annularly aligned in relation to one another and to the Be brought into alignment. Furthermore, intermediate areas 11, 12 and 13 are of reduced cross-section between the rear areas of the wedges and the front areas of the handles are provided, which break off or sever the handles of the inserted wedges facilitate, as the intermediate areas H and 12 with already described embodiment. The rear areas of the handles H1, H2 and H3 are, for example, made in one piece with them formed webs W4 and W5, the articulation points form, connected to each other. These bars allow the wedges and handles to move in a pincer-like manner like the web V / 3 in the embodiment already described.

In a further comparison with the embodiment already described shows, in particular with reference to a'f Fig. 9 and 11, that the opposite Internal flats of the wedges V / 1, V / 2 and V / 3, the intermediate areas H, 12 and 13 and the handles H1, H2 and H3 are essentially cylindrical and have a common passage or a guide P (Fig. 9) which extends through the wedges, the intermediate areas and the handles. When the wedges and handles are spread around the articulation points or webs V / 4 and V / 5 in a pincer-like movement have been, the guide P for receiving the string S is open (Fig. 1). V / hen the wedges and handles around the pivot points or webs V / 4 and W5 have been closed in a pincer-like movement, bring the cylindrical ones Inner surfaces of the wedges, intermediate areas and hand

13Ö0SÖ / QU3

gripped the inner surfaces of the wedges axially and in a ring shape relative to the string S for alignment.

As in the previous embodiment, the handles H1, H2 and H3 are operated by one hand of a user grasped to move the aligned wedges along the string and insert the wedges into a tapered hole, which extends through the frame of a racket for ball games so that the end portion of the string S can be attached to the frame F.

Structural details of the spring pliers of the embodiment shown in Fig. 9-12 correspond to those of the spring pliers according to FIG. 6. Furthermore, the spring pliers 100 according to FIGS. 9-12 can also have radially outwardly projecting projections 64 and 66 as shown in FIG. 8, the handles in relation to the hand of the user in their Determine location so that the back and forth movement of the handles relative to the inserted wedges in one Arc in a plane substantially parallel to the opposing inner surfaces of the wedges is facilitated to reduce any tendency for the inserted wedges to withdraw from the hole, caused by movements of the inserted wedges due to the breaking of the intermediate areas from the wedges caused.

As in the case of the opposing inner surfaces of the wedges W1 and W2 in the previously described embodiment the opposing inner surfaces of the wedges W1, W2 and W3 can move inwards as a whole be tapered from the rear to the front linden of the wedges, so that the opposing inner surfaces of the Wedges after swiveling the wedges apart, intermediate areas and handles around the bar in a pincer-like movement to enable the inclusion of the S string in the

I 30050 / 0U1
